lwM2M OTA for ESP8266
3 likes2,717 views
The document discusses the OTA (over-the-air) firmware upgrade process for the ESP8266 microcontroller, highlighting various hardware options and software tools available for development. It outlines a project involving the integration of the Wakaama LwM2M with ArduinoOTA to enhance firmware updates and control from platforms like Leshan and Hawkbit. The author, Manolis Nikiforakis, mentions plans to develop this as an Arduino library, with a deadline for completion set for February 26.

- 12. OTAXM 1. Port Wakaama (lwM2M) to ESP8266 ○ some coap enpoints ○ attempt merging with ArduinoOTA (?) 2. Make it an Arduino Library ○ enrich coap endpoints ○ improve ArduinoOTA - Wakaama merge 3. Control ESP8266 from Leshan ○ and Hawkbit in the future Alternative approach: enrich Arduino microcoap with wakaama enpoints and modify ArduinoOTA to include lwM2M compatibility
